Kubota dozer blade angle cyl replacement

[doublek]

I need a replacement single acting angle cyl for a Kubota angle plow - series KUFD 110 SN 2039- M-233 painted on plow was made by a company called chromalloy (now Amerequip New Holstien Wisc.) about 30 years ago.
They can't help me- Kubota cant help me- maybe some one here can! the cyl is a welded unit - I only need something close as it can go a little more or less left and right as I am plowing snow with it.
I bought it used and used it with out any problems for 10 years and apparently got some dirt or cinders on the piston and scoured it. - I also would consider buying a pair to replace both if cost is reasonable or a double acting cyl if I can just vent the one port? - maybe a used one from a tractor salvage company?
here are the measurements and pictures of the cylinder:

the ram cyl. I need has a 2 1/4 in.piston dia.

2 3/4 in o.d. tube dia 21/4in ID

thanks

3 1/4 in o.d. collar dia welded to tube

20 1/2 in extended

about14in colapsed (can't tell exactly because it binds on scour)

the opening between the clevis ears is 3/4in both ends

the clevis pin is 3/4 dia

1 1/2 in clevis center pin distance to tube end

2 1/2 in clevis center pin distance to piston end
only one hyd connection

would like to also buy some kind of plastic or rubber bellows to slip over pistons to protect them
Thanks

Look at this one .

3X20X1.5 DA HYD CYL HEAVY DUTY CLEVIS

For single action. just put a breather vent in the other port.

3o 1/4" long retracted I need about 14" retracted about 20 " extended but thanks anyway!

Have you priced having it rebuilt, if it's that difficult to find?

Pistons do not usually have bellows/covers/etc... they are chromed and the combination of hydraulic oil and the constant wiping of the seals keeps them pretty much mint. Bellows would probably trap moisture when they were sitting and make rust worse. Once everything is in working order they will give you a good service life without a cover.

My next step is to look into getting cyl rebuilt I need to get a machine shop to cut off the welded collar to see if the tube is salvagable - my cyl piston is scoured on both sides so it might have a slight bend
used it for 10 years without any problem- may have to have a hyd shop make up a new custom one

It might be cheaper to get 2 of this one and change the mounts.
2x6x1.4375 SA HYD SNOW PLOW CYLINDER
The next one up would be this one. 2x10x2 SA HYD SNOW PLOW CYLINDER

2x6 may work I have a welder can make up conversion from pin to clevis may loose a little stroke but no biggie probably a lot cheeper to change both cyl spec says max 2500 psi where can I find max pressure rating for Kubota L3430 hydraulics?
thanks for the info

L3400 Work Shop Manual indicates 2276 psi to 2347 psi as the range for the hydraulic system relief.

Might be the same as L3430

You said you might loose a little stroke. You are at 20 1/2" extended now, the 2X6 in the link is 19 1/4" just move the new mount in a hair. Don't think you well find anything much better. The 2X10 you would have to move the new mounts way out.

I was measuring end of tube to end of piston I need to add 21/2+11/2in for the clevis pin distance still close enough I think it will work hyd pressure looks good also
thanks
